EBERHARD SCHNEIDER, or -NEW YORK, N. Y.

MOVING-PICTURE-RQJECTING APPARATUS.

To all whom t may concern.'

Be it known that I, EBERHARD SCHNEI- DER, a citizen of the United States and a resident'of the borough of Manhattan, in the county of ,New York and State of New York, have invented certain new and useful Improvements in Moving-Picture-Projecting Apparatus, of which the following is a specification, 9 l

.This invention relates to a moving picture projecting apparatus, and its novelty is directed particularly to its collapsible features.

lVitlh this apparatus, a frame has formed therewith a p'air of film magazines with their axes concident. The elements of a picture projecting apparatus are mounted on a frame plate, which latter is pivoted to the frame` of the machine and which can be located ina vertical position when in use and can be swung to a. horizontal position adjacent to the frame when not being used. A lamp is pivoted to the frame which, when in use, is normally in a horizontal position, and which can be swung at right angles to this position and located adjacent to the frame of the machine. l The invention speciically comprises amon its improvements a lamp connected to a condenser shell having a resistance coil wound around the body thereof, to allow the lenses in said shell to cool gradually when the source of light is extinguished and to prevent said lenses from cracking.

The, propelling mechanism of the invention. has incorporated therewith sprocket drums with sprocket chain wheels, operated by a chain comprising balls that are Hexibly connected, and by virtue of the chains, the sprocket wheels with their drums can be journaled with their axes inclined to each other. This disposition of the drums allows the ilm magazines of t-heinvention to be placed side by side.

Provision is made to view the ilm as it is wound-up on one of the lm reels of the apparatus. v

An arm 333 with the handle 334 extends from the other end of the -barrel`330. To operate the ma# chine'the barrel330 encircles the pin 231 and .the hook 332 locks with the pin 238 of the sprocketdrum 235. 1n the crowns of' the- 5 magazines 2l and 22 are 279 havingv framing device is produced.

formed openings '340, 341, and guide rollers 342 and 343 are journaled to the frame 20 adjacent to said .fopenmgs f `The film 202 extends from :the reel 250 through the opening 340 over the roller 342, It then passes over the guide roller 264, sprocket drum 256, thence under the film clamp 192, in the pathof the opening'155,

' in the-frame plate 150. The film then is engaged bythe sprocket drum 235,' leads over the roller 341 into the magazine 21 to be.`

wound vup by the reel 251. v

The adj ustmets and Voperations of the elements of the apparatus have been described. A particular novelty of the invention consists inthe collapsible feature of its elements, Yby means of which the frame plate 150, with its element for propellin the lm 202 can be swung from the vertical position shown in the drawings to a horizontal position, sothat the swinging end of said frame plate bears on the horizontal abutting face 35 of the bracket 34 and locates said frame plate 150 adjacent to the frame 20. yA seeond novel featureof the invention. consists vso in the means described VVto vswing the'lamp with its appurtenances on the pivot 36 to assume'a vertical position adjacent to the frame 20. AThese novel collapsible features enable the apparatus to be packed inl a case of small dimensions. j

The coillof 4wire 120 constitutes la resist-l ance coil or rheostat for the Vcurrent that energizes the carbons 118.' Itobviates the necessity of an independent rheostat and its heat after lthe electric current is shut olf; en-

ables the lenses 70 and 71 to cool .gradually and prevents them fromcraclnng.

The' adjusting arm 173.and t eappurtenancescontrolled thereby, allowsl the spindle 164 with the shutter 165, andthe gripping pin support' 305 with its gripping pins 309, to be vertically adjusted, to' locate. the film 202 in'proper reglster/With'the opening 155l 'in the frame plate,'rand thereby an efficient The chain with the balls or spheres 278 permits the easy and ecient connection of 4the sprocket Wheels 237, 251 and 170, that -tulljn in planes making angles with each ot er.

'.,the axis of the upper ysprocket drum4 256 4with theframe plate 150,- adjusts the, film 202 so that it can easily'leave thema azine -22 and .wind around said' drumr an then easily be located Vunder the clamp 192.-

.Various modifications may be made inthe ido Thel 'inclination of forty-fiveildegrees of construction shown without departing .from

the spirit of the invention.- The resistance coil 121 might be located on the inside of the condenser shell'58, or it might be located on theoutside or inside of thesleeve or other portion of th lamp. ff j Having' described my invention, what `I desire to secure lby Letters Patent and claim is:
